This may not belong here, as it isn't specific to PG products. I have miles of wire running around my room, and have a method for keeping track of 'em. I save those bread bag plastic clips, not the wire ties, the flat plastic ones and when I plug something in somewhere I write where they go on them with a sharpie. Both ends get one that is their destination. On my mixer I have a gang of wires, some not plugged in, so when I need the thing they go to, I find the right tag and plug them in and re-label the faders and knobs. I get it right every time. Some even come in colors, so I can look across the room and say "Oh yeah, the red one."
